It partly depends on what you’re taking the medications for. Uncomplicated panic disorder without agoraphobia has the highest rate of complete remission. Severe obsessive compulsive disorder, agoraphobia, or social anxiety disorder may require some long term medication to maintain remission. Generalized anxiety without serious depression may respond fully to CBT. A lot will depend on how good the CBT is and how hard you are willing to work on it. For OCD I recommend Brainlock by Jeffrey Schwartz. For panic disorder proper breathing is essential. The following link has instructions for proper breathing.
